GRAIN-DOOR.

Application filed. January 6, 1913.

To all whom it may concern:

Be it known that I, BENJAMIN MILBERT, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Grain-Doors, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to grain doors for freight cars.

Prominent objects of the invention are to provide a simple, practical and inexpensive form of grain door; to arrangefor the easy and ready opening of the same; to prevent sticking or binding on the part of the door and preferably to allow the grain itself to automatically open the door; to provide for the ready filling of the car with grain; to make it impossible to damage or abuse the door in endeavoring to unlock or open it, and also to make it impossble to damage the door posts in endeavoring to lock the door; to arrange to get the door entirely out of the way when desired; and to accomplish the foregoing and other desirable results in a simple and expeditious manner.

In the accompanying drawings, Figure 1 is an elevation looking from outside of the car of a grain door embodying my present invention; Fig. 2 is a view of one side of the door looking outwardly from within the car; Fig. 3 is a view of a door in an elevated and suspended position; Fig. 4 is a vertical section taken on line 4 l of Fig. 1; Fig. 5 is a cross sectional view similar to Fig. 4:, but showing the door partially elevated; Fig. 6 is a cross section of one side of the door frame and the adjacent portion of the door, and Fig. 7 is a view similar to Fig. 4 showing certain parts associated with the door in a changed position.

In the accompanying drawings I have shown part of the side wall 1 of a freight car, and posts 2, 3, for a door therein, the floor of the car being shown at 4. The door 5 is preferably made of metal and is adapted to fit and swing between the posts 2, 3. The door is pivotally supported so that it can swing between the posts 2, 3, a convenient arrangement being to provide the upper edge of the door with a horizontally extending bar 6 having notches 6 and having upturned ends 7 --7 which are provided with pivots 8-8, and provide the posts 2, 3

with metal pieces or plates 99, secured thereto as by screws 1010, Figs. 4 and 5, which said plates 9-9 are provided with grooves or recesses 11-11, in which the pivots 88 can fit and on the lower end of which the same can rest. When the pivots 88 are at the bottom of the grooves 11-11, the door 5 extends substantially to the floor 4:, the latter preferably being provided with a plate 14 below the door on which the latter can rest. Thus the door 5 can be swung outwardly between the posts 2 and 3, and of course when so swung outwardly will permit grain to unload from the car. The door will be automatically opened by the weight of the grain, it will be seen, in case the doc-r hangs free, allowing the weight of the grain to act.

As an arrangement for holding the door in place and locked against the weight of the grain. the door is shown provided with a catch 15 adapted to fit into an aperture in the plate 14, whereby when said catch is in said aperture, said door will be locked in closed position. A further locking arrangement is shown, the same consisting of metallic plates 1616, arranged at each side of the door, and on the inner sides of the posts 2 and 3, said plates 16 being preferably pivoted at their upper ends by pivots 18 to arms 19 on the door 5, and being provided with lugs 20-20 which pass through apertures 2121 in the door, the lugs 20 being provided with vertical apertures through which wedge-shaped keys 22-22 may pass, the keys 22-22 being hung from the door 5 by chains 23. Thus it will be seen that the plates 16 hold against the rear or inner sides of the door posts 2 and 3, and are locked to the door 5, by the lugs 2020, and pins 2222, so that said arrangement serves as a lock to hold said door in closed position. The plates 16 ordinarily swing free of the door, but may be locked thereto by lugs 20 and pins 22.

It will be seen that the door 5 is not the full height of the door-way, but is only a portion of the same, perhaps two-thirds, more or less, and that there is an open space 25 above said door through which grain may be loaded when the door is closed. The door may be elevated and then swung up out of the way by raising the door so that the pivots 88 slide up in the grooves 1111, and then come into position of rest at the lower end of a small supplemental pended from the roof 29 of the car.

r a hook 32 by side of the car groove 26 formed laterally from the upper end of the groove 11, the door be'ng shown in such elevated condition in Fig. 5. The

door may then be swung upwardly toward the roof of the car as shown in Fig. 3, the plates 16 being swung upwardly, of course, with the door. The door may be held in this elevated condition by'a hook 28 sus- This hook 28 has ends or prongs 30 adapted to fit in apertures 3l-3l, (Fig. 1) in the car door. The door is which the door at the other can be held in elevated and swung-up position.

It will be seen that the door can be easily locked and unlocked and can be readily opened by swinging outwardly, and so can be much more easily manipulated and operated tounload the grain than if it slid horizontally or vertically. It will also be seen that the grain itself can swing thedoor open as soon as unlocked, thereby making it unnecessary to exert any labor to open the same. It will also be seen that the door can be readily locked by the locking devices, and also that the door posts are protected against damage as by driving in bolts, etc., in an effort to lock the door.

.Itwill be understood that the grain door herein shown can be used in connection with the usual sliding freight car door if desired, the latter being outside of my improved door. 7 Y

The notches 6 on the bar 6 are to permit the opening of such a sliding door if one is used. The notches may serve as fulcrum Copies of preferably provided with points for an opening rod or lever which may be applied to one edge or a part of the door to pry it open. By having the notches arranged at intervals along the bar 6 the rod or lever may be applied at different points so as to apply more easily to the end of the door as the same becomes more and'more open.

It will be understood that changes and modifications can be made without departing from'the spirit of the invention.

WVhat I claim is: p

1. In combination with door posts, a vertically swinging between't-he posts and substantially closing the opening between them, verticallyswinging members pivoted to said door and'extending throughout the length of the side edges of said door, and said members extending across the door and door posts. 7

2. In combination with door posts, a door extending between said posts and substantially closing the opening between them, said door being vertically movable and hinged to said door posts, a vertically swinging member pivoted to said doorand constructed to extend along the side edges of said door and across the adjacent edges of said door and door posts. 7

In witness whereof, I hereunto subscribe my name this 13th day of December, A. D. 1
